The popular 65 mm format, as measured from hub to hub, is often considered to be about the smallest you can make an FPV drone without making serious compromises. Which is exactly why [Hoarder Sam] decided to make a smaller version that can fit inside a Pringles can, based on the electronics used in the popular Air65 quadcopter from BetaFPV. The basic concept for this design is actually based on an older compact FPV drone design called the ‘bone drone’, so called for having two overlapping propellers on each end of the frame, thus creating a bone-like shape. The total hub-to-hub size of the converted Air65 drone ends up at a cool 22 mm, merely requiring a lot of fiddly assembly before the first test flights can commence. Which raises the question of just how cursed this design is when you actually try to fly with it.
